The location and track alignment of the Dominion LRT station in the City of Ottawa presentations of April 25 and June 17, 2013 show the proposed Dominion LRT station at the foot of Berkley and Dominion Avenues on the grassy area and footpath from Dominion to Scott Street. This alignment would force the destruction of a grove of trees that are a sound buffer from Parkway noise for The Barclay condominium (94 apartments) and the Plaza Towers apartment building (190 apartments). In addition, this wooded area is on the path from the office building at 495 Richmond Road to the Dominion station and is used as part of the walking, bicycling, snowshoeing and skiing path from Scott Street to Cleary Avenue and beyond on the southern side of the Parkway.
We are proposing that the station be moved some 50 metres north into the existing Transitway trench. This alignment would save the grove of trees and could be easily accomodated by slight curves in the track which are well within the capacity of the Alston Citadis trains that have been chosen for the Ottawa LRT system. In addition, the City’s drawings show the station on top of a major trunk water main serving western Ottawa and Kanata as well as sewer and gas lines in this area. It is completely unnecesary to add some 50 metres of expensive excavation in the hard limestone rock at this location when the existing Transitway trench is already there. It is certainly inadvisable to excavate on top of the trunk water main which is only 4.3 metres underground at this location. Apparently some City staff and/or Delcan consulting staff have said Alstom trains cannot curve around this location. However, the City of Ottawa’s promotional video (at minute 6:00) show a Citadis train negotiating a much tighter curve on a European street than would be required here. Further, Alstom’s specifications for the Citadis show a minimum turning radius of 20 metres, while the main Ottawa LRT line is using some 50 metre radius turns, and this particular change in alignment would require only a 100 metre radius turn in a section where trains are moving slower into or out of a station.
